TILE-DIPPING MACHINE.

EiPECIFICATION forming part of Letters Patent No. 642,135, dated January30, 1906. Application filed April 8, 1899. Serial No. 712,221. (Nomodel.)

To aZZ whom, it may concern:

Be it known that we, AUGUST 1V. KOCH, re-

siding at Cincinnati, in the county of I'Iamilton and State of Ohio, andCHARLES F. Kocn, residing at Covington, in the county of Kenton andState of Kentucky, citizens of the United States, have invented certainnew and useful Improvements in Tile-Dipping Machines; and we do declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the figures of reference marked thereon,which form a part of this specification.

This invention relates to certain improvements in machines for applyingcolor, glaze, or the like to tiles and other articles before firing; andthe object of the invention is to provide a machine of this characterwhich' shall be simple and inexpensive in construction and having meansfor mechanically feeding the tiles or other articles in a substantiallycontinuous manner, so that the operation of the machine is improved andits out put increased and the labor in supplying the articles to andremoving them from the machine is lessened.

The invention consists in certain novel features of construction,combination, and arrangement of the several parts of the improvedmachine whereby certain important advantages are attained and the deviceis made simpler, cheaper, and otherwise better adapted and moreconvenient for use than various other coloring and glazing devicesheretofore employed, all as will be hereinafter fully set forth.

The novel features of the invention will be carefully definedin theclaims.

In the accompanying drawings, which serve to illustrate our invention,Figure 1 is a side elevation showing a machine constructed accordingtoour invention, and Fig. 2 is a plan view of the same. Fig. 3 is avertical sectional view taken transversely through the machine in theplane indicated by line a; a: in Fig. 2.

In the views, 1 indicates the frame of the machine, having at its endssupporting-legs and formed with a widened central part 2.

3 indicates the feed-trough,preferably hiade inclined and having raisedsides to facilitate the feeding of the tiles or other articles placed onit to the machine. The feed-trough is located at one end of the frame 1,and at the other end thereof is arranged a delivery-tablo 4 to receivethe articles after passing through the machine.

At one end of the frame 1, near the feedtrough 3, is arranged atransverse drivingshaft 5, having tight and loose pulleys 6, so that themachine may be operated by a belt from any convenient source of power,and said shaft 5 is coupled to drive, by means of toothed gears 7, ashaft 8, parallel to it and having at its central part, between the sidebars of which the frame 1 is formed, a wood roll or pulley 9, over whichpasses the bight of an endless carrying-apron 10, extending lengthwiseof the frame between the side bars thereof and supported on idler-rolls12,held on shafts 11 transverse of the frame. The idlers 12 are arrangedin two groups or series of three each, one series at each end of thecentral wider part 2 of the frame, and said idlers serve to sustain thecentral part of the endless apron 10, the last idler of the rearmostseries receiving the bight of the apron. The shaft 5 also carries,outside the frame, a pulley 13, over which passes a belt 14, extendingover a pulley 15 on a shaft 16, journaled transversely of the centralwider part 2 of the frame and geared, by means of bevel-gears 17 at itscentral part, to a vertical shaft 18, which extends down into acone-shaped colortub 19, arranged beneath the wider part 2 of the frameand adapted to hold the coloring or other material in liquid form. Theshaft 18 has blades 20 within the tub 19 to agitate or stir the liquidtherein to maintain the desired consistency thereof. The shaft 16 isalso provided with a pulley 21, over which extends a belt 22, leadingaround a pulley on a pumpshaft 23, journaled transversely beneath theframe and serving to operate a centrifugal pumping device 24, to whichthe liquid from the tub 19 is supplied by means of a pipe 25. A pipe 26leads from the pump 24 abovethe frame, extending up along one of theuprights or standards 28 of a yoke which extends across the wider partof the frame, and said pipe connects with a flexible hose 29, on the endyoke to deliver its spray upon the tiles or other articles carriedthrough the machine beneath said yoke upon the endless apron 10.

A sheet-metal hood or guard 30 of conical form is arranged beneath thespray-nozzle 27 over the shaft 18 and gears 17, so as to protect thesame and prevent clogging of the gears with the coloring or othermatter, the conical sides of said hood serving to return the liquid backinto the tub 19. The lower part of the hood 30 is by preference formedwith a circumferential depression or hollow 31, having in its bottomapertures 32, acting as-a strainer to prevent particles of foreignmatter from passing into the tub.

In operation the tiles or other articles to be coated are placed uponthe feeding-trough 3 and pushed successively therefrom onto the endlesscarrier or apron 10, as indicated at. T in Figs. 1 and 2, the upper runof the apron being substantially level with said trough to facilitatethe feeding of the articles. The articles are carried by the apron alongthe frame beneath the yoke at the wider part thereof and are given thedesired coat of coloringmatter, glaze, or the like in the form of a finespray by means of the nozzle 27, which by reason of the flexiblehose-section 29 is capable of adjustment to deliver its spray at anydesired angle, so that the color may be regulated at will. The articlesafter being coated are delivered by the apron to the delivery-table 4,which is preferably set slightly below the plane of the upper run ofsaid apron as seen in Fig. 1, so as to facilitate the delivery of thearticles.

From the above description it will be seen that the machine constructedaccording to our invention is of an extremely simple and inexpensivenature and is especially well adapted for use, since its permits offeeding the articles to be coated to the machine in a continuous manner,so that stopping of the machine to apply and take off each article isobviated and the articles are evenly and uniformly coated. the abovedescription that the machine is capable of considerable modificationwithout material departure from the principles and spirit of theinvention, and for this reason we do not wish to be understood aslimiting ourselves to the precise form and arrangement of the severalparts herein set forth.

Having thus described our invention, we claim- 1. In a machine of thecharacter described, the combination of a frame, an endless carrierextended thereon, a nozzle, a reservoir, a pump, a pipe extended betweenthe reservoir and the pump and arranged to supply color- I ing-matter,glaze or the like to the pump from the reservoir, and a flexibleconnection between the pump and the nozzle for supplyingcoloring-matter, glaze or the like from the pump to the nozzle whilepermitting adjustment of the nozzle in directing the discharged sprayupon the articles held by the carrier, substantially as set forth.

2. In a machine of the character described, the combination of a frame,a carrier thereon, a nozzle arranged above the carrier in position todischarge coloring-matter, glaze or the like in finely-divided form tothe articles held by the carrier, a reservoir for containing a supply ofsaid coloring-matter, glaze or the like, said reservoir being arrangedbeneath the carrier in position to receive the surplus coloring-matter,glaze or the like from the nozzle, a shaft extended across the frameabove the reservoir, an agitator-shaft having an agitator for stirringthe material in the reservoir, gearing between said shafts, a shieldarranged over the gears and also extended over the reservoir, and astrainer carried by the lower edge of said shield to strain the materialdischarged thereon from the nozzle,substantially as set forth.
